have mutual trust
Please don't doubt the teacher's care for the child when the child is unwell. If you are really worried, have you considered letting your children rest at home instead of sending them to school?
Respect and support
Parents who really think about their children know how to give their teachers enough respect and support, instead of endless "demands" and "suggestions", so that teachers are at a loss on the road of education.
cooperate
Let's work together for the children!
